Here's the straight poop on it from this quarter's Additive Fabrication Spy
(TM) Newsletter:
* "3D Systems has had a couple of patent applications published this period
for what might be next-generation photopolymer-based technology. One describes
the use of an endless transparent belt to provide thin, bubble-free layers
of photopolymer at the top of a build stack. Area-wise exposure is done
through the belt using a spatial light modulator such as a deformable mirror device
(DMD). A second patent application presents methods of increasing the
resolution and edge smoothness parts fabricated with such exposure devices. In
addition, specific photopolymer materials with characteristics which fit the
process are being explored by the company."
